Hi. Usually when I want to install a new version of julia kernel for use in a jupyter notebook, I follow the follow these steps:

1. Install julia (say v1.5.1)
2. Run julia from a command line.
3. `julia> using Pkg; Pkg.add("IJulia")`
4. Quit julia
5. Run `jupyter notebook`
6. The new kernel is available under the New tab.

However, trying to install 1.5.1, steps 1-5 proceed as usual, but I’m not seeing Julia 1.5.1 as an option. I can’t figure out what’s different this time.

(FWIW this is on an ubuntu machine.)

Thanks for any help or tips.

`Pkg.build("IJulia")` (probably).

Yes, thanks! I wonder why I didn’t have to do that previously. Or maybe I forgot to note it down. Won’t forget next time!
